Full Changelog

Vendoring Argon2 @ f57e61e.

Added

• Python 3.15 wheels. #112

• PyPy 3.11 wheels.

• Linux on RISC-V 64bit wheels. #106

• pyemscripten wheels for Python 3.13 and 3.14. #129

Changed

• The bindings are now built with scikit-build-core and CMake instead of setuptools. The C source for the extension module is generated from _ffi.cdef.txt and _ffi.csrc.c using CFFI's cffi-gen-src tool and committed to the repository as _ffi.c. The build compiles that file directly and needs no CFFI at build time. Building from source requires CMake now. If none is found, it is downloaded automatically as part of the build. #173

Removed

• Python 3.9 support. #173

• Python 3.13t wheels. Free-threading on 3.13 was always only experimental and both manylinux and cibuildwheel dropped support for it.
